<p>The method for reducing the noise generated in a light sensor supplying an initial electrical signal (x(t)) of periodic type, comprising a useful zone (U), a reset zone (R) and a reference zone (B), comprises delaying said initial electrical signal (x(t)) to obtain a delayed electrical signal (x(t- tau )), subtracting the delayed electrical signal (x(t- tau )) from the initial electrical sign (x(t)), to obtain a difference signal having redundant portions and limiting the output signal at one of the redundant portions, through a clamping diode (24). The output signal is then limited as regards at least some of the unnecessary components and has a reduced amplitude, thus making it possible to increase the dynamics of the useful portion. <IMAGE></p> |
